SkyView v3.5.1: CopyWCS and SIA fixes

We have just released SkyView v3.5.1 which has a couple of fixes that shouldn’t affect most people. A bug in the handling of the CopyWCS keyword has been fixed. CopyWCS is a keyword which allows a SkyView-in-a-Jar user to specify that the output geometry for some request is to be the same as some existing image. E.g., if you have a WISE image of a given region and you want a DSS image of exactly the same spot, you can use CopyWCS instead of position, size, pixels, scale, projection, coordinates and such.

The other change is to some of the metadata returned when making VO Simple Image Access requests. All input parameters are now described as strings which is consistent with SIA specification.
